DHAKA, Feb. 14 (Xinhua) -- A Bangladesh based group has claimed that nearly 20,000 Indian websites including that of the the country's Border Security Force or BSF got hacked until Tuesday after hackers from both the South Asian neighbors locked in a " cyber war" since last month.

The group -- Bangladesh Black HAT Hackers -- in its Facebook fan page writes, "India (hackers) hacked our 400 sites (May be less) in total, We hacked 20,000 (100/200 may be less) sites in total since the war started."

The hacking group claims that the BSF website (www.bsf.nic.in) was completely damaged after it got hacked.

A Bangladesh government official was not immediately available for comments.

Some postings in social media including Facebook and LinkedIn have reported that the ongoing cyber war between the hackers based in India and Bangladesh, which share a border of more than 4,000km (2,485 miles), have mostly targeted government websites.

Apart from Black HAT, two more Bangladseh based groups -- Expire Cyber Army and Bangladesh Cyber Army -- have also reportedly locked horns with Indian hacking groups including Cyber Army and Indishell.

The Black HAT said that their action was in response to the killings by the BSF personnel in the Indo-Bangladesh border.

"We don't have any personal issues with Indians. But the brutality of BSF as well as Indian government has forced us to do this," One hacker belonging to the Black Hat posted in its Facebook fan page.

The Bangladesh based groups, which are reputedly getting support from many foreign hackers, after defacing many Indian websites urged the Indian government to ask its border guards to stop killing innocent Bangladeshis along its boder. "BSF, Stop killing Bangladeshis at border."

".... the Indian guards kill one Bangladeshi every four Days!" hackers wrote on a hacked Indian website.

Bangladesh's Ministry of Foreign Affairs in a statement on Sunday said any incident of torture, killing and opening of fire on Bangladeshi citizens by India's BSF is unacceptable.

The statement comes after the BSF chief UK Bansal's recent remarks in an interview to media in which he reportedly said it would not be possible to stop firing totally along the border that separates the two countries so long as criminal activities continued.

Bangladesh's foreign ministry which later last month also lodged a protest with the Indian side noted that recurrences are taking place despite categorical assurances at the highest level of the Indian government for exercise of maximum restraint by the BSF.

Odhikar a Dhaka-based human rights monitoring group last month said India's BSF killed 31 Bangladeshi nationals last year when the killing of a 15-year-old girl Felani who was shot dead after she got entangled in barbed-wire fence on the Indian side, was a much-talked-about incident.
